It presents no features not common to Chamba, the next succeeding province to the north-west. Sultanpur, the capital, is 5000 feet, Kangra Fort, situated a short way' within the outer ranges, is a British station, and the hills around it are extensively planted with tea. Dharmsala, above Kangra, is a sanitarium, elevated about 6000 feet. The chain bounding the Satlej on the west is considerably higher than that on its east bank, and is crossed into Suket by the Jalauri Pass, elevated 12,000 feet. Mr, Edgeworth is the only botanist who has investigated the flora of this province, and he has (since the printing of p. 70 of this Essay) communicated a valuable collection to Sir "W. Hooker's Herbarium. 5. CHAMBA. Chamba, the next province to Kulu, is altogether like it in physical features, and consists of the mountain basin of the Ravi. It has been traversed by Dr. Thomson, who entered it from the north-west, by the Eadri Pass, elevated 11,000 feet, over the chain dividing it from Jamu; thence he descended to the Ravi, in the centre of the province, where its bed is elevated less than 5000 feet; and travelling northward, left it by the Sach Pass, elevated 14,800 feet, over .the range divi- ding it from Kishtwar. The vegetation of Chamba appears to present few peculia- rities, amongst which we may notice the appearance of Cra- t&gus Owyacantha, which here finds its eastern limit; Lits&a consimilis, Rhododendron lepidotum, and Sibbaldh, purpurea have not hitherto been detected further to the west. Father" fftlla involucrata is a carious example of a plant suddenly appearing most abundantly, and continuing so for several provinces 1o Hie westward.
